PRECISION AT THE GATEWAY
Abergavenny’s wind patterns demand expertise.
The Blorenge and Sugar Loaf create complex downdrafts that destabilize standard drones. We use CAA GVC-authorised flight logic to maintain stability over heritage stone.
Our surveys are designed for clients who value preservation over repair:
- ✅ Listed Building Compliant: No physical contact, no disturbance.
- ✅ Stone Tile Delamination: Spot flaking before it slips.
- ✅ Chimney Mortar Erosion: Critical for party-wall disputes.
Don't Ask a Roofer if You Need a New Roof
We are Independent Data Collectors. We don't fix roofs, so we have no incentive to "find" extra work.
1. The Incentive
The Roofer: Makes money by finding defects, selling materials, and increasing the job scope.
CalonTerra: We charge a fixed flat fee. Our price is the same regardless of what we find.
2. The Evidence
The Roofer: Often relies on verbal opinions or blurry ground photos.
CalonTerra: A downloadable Visual Condition Report with zoomed-in 4K evidence.
3. The Cost
The Roofer: You may pay for access (ladders) just for an estimate.
CalonTerra: A small fee for the truth. Only pay a tradesman to fix the damage you can see.
